UPDATE:  You probably need to edit this via Group Policy instead  -- this is an example of the group policy for kernel mode drivers for printers:

1. Open Group Policy Management and open the Default Domain Controllers
policy. NOT the default domain policy.
2. Double-click Administrative Templates, and then double-click Printers.
3. Right-click Disallow installation of printers using kernel mode drivers,
and then click Properties.
4. In the Setting tab, click Disabled, and then click OK.

and therefore poorly-written kernel-mode drivers can cause stop errors.
